Regard this as the starting point,this paper deduces the random error formula of the filling and opening fractured rock mass by using the transmission law of the error and calculates the error combined with the actual project.

• 以此为出发点,利用误差的传递定律推导出了充填裂隙岩体和张开裂隙岩体的随机误差计算公式,并结合实际工程问题分别对充填裂隙和张开裂隙两种情况下利用随机误差公式进行了的误差分析。
